Electrical Code Regulation. 1.4 INSTALLATION.1 Provide cable trays in approximate location and general routing as shown on drawings optimize routing to minimize cable lengths and provide best access for future installations..2 The Contractor shall supply and install a system of cable raceways consisting of a combination of cable tray, conduit and J hooks. The cable trays extend horizontally from the Communications rooms, down the hallways or corridors to become the backbone or main pathway to support communication cables. Each Communications outlet shall be connected to the nearest cable tray with conduit or J hooks depending on site access U.B.C. Information Technology Page

2 conditions. J hook to be sized for the outlets and or number of cables it will hold allowing for some expansion. (Refer to Standard Drawing ITSTD-29).3 All raceway, J hooks shall be installed parallel to the building lines, keeping cable run length at an absolute minimum..4 In open office environments, the preferred method of extending the conduit from the outlet to the cable tray is via perimeter walls. If this is not possible then use Pac poles or run in "pony" walls..5 Where raceway size is not specified, the raceway shall be sized to not exceed a 40% fill ratio after all the cables are installed. Where there are zero bends in the raceway, the fill ratio may be increased to 50%.

Daisy chaining outlets is a practice that is to be minimized to special circumstances and used only with the approval of UBC IT..9 When zone conduit is used, install in each room ceiling space entered a minimum 300 mm X 300 mm X 150 mm deep pull-box. Conduit to communication outlet shall be from this pull-box..10 Cable trays are usually installed in the false ceiling space of hallways and located to keep conduit lengths to a minimum. When raceway is not installed in a readily accessible false ceiling space, access hatches shall be installed at a nominal spacing of 9 Meters. Additional access hatches must be provided at all sections of tray where a change of direction occurs. Additional hatches must be provided wherever there are drop conduits intersecting the tray..11 Conduits and cables containing line voltage conductors (including branch circuit wiring) shall not be supported from the supports used for communication cable trays or from the communication cable trays themselves..12 Provide cable support dropouts at locations where cables exit the cable tray and the combined weight of the cables can cause deformation in any of the cables in that bundle..13 Cable trays may require installation of risers, bends, etc. to adjust tray up or down as well as sideways for the tray routing to fit within limits of space available, and to clear other services, ducts, pipes etc. along the route. Routing may be adjusted somewhat as necessary to enable installation of services under other trades. The above field adjustments are to be done at no extra cost to the Owner..14 Where tray runs change elevation; a manufacturer recommended solution must be used. U.B.C. Information Technology Page
